fix: renormalize gradlew.bat so a fresh clone is clean

[jamesarich]

The problem

git status is dirty the instant you clone, before touching anything:

$ git clone https://github.com/meshtastic/kzstd && cd kzstd && git status --porcelain
 M gradlew.bat

.gitattributes declares gradlew.bat text eol=crlf, so git expects the blob stored in the repository to be LF and the working-tree copy to be CRLF. The committed blob is CRLF instead — it predates the attribute. So git checks the file out as-is, re-hashes it through the clean filter to LF, and reports a modification that can never be resolved by editing.

git ls-files --eol names it directly:

i/crlf  w/crlf  attr/text eol=crlf     gradlew.bat      # before — index should be i/lf

Not a local configuration problem. I checked fresh clones under both core.autocrlf=false and core.autocrlf=input; both are affected, because a path attribute overrides autocrlf either way. Every clone of this repo has this.

The fix

git add --renormalize gradlew.bat. The blob becomes LF, the checkout stays CRLF as the attribute intends:

i/lf    w/crlf  attr/text eol=crlf     gradlew.bat      # after

The diff is 82 lines each way and is entirely line endings — git diff --ignore-cr-at-eol is empty. Windows users are unaffected: the working-tree copy is still CRLF, which is what eol=crlf guarantees and what cmd.exe needs.

Verification

Cloned the branch fresh: git status --porcelain is empty, and stays empty after deleting and re-checking-out the file.

Why it's worth fixing

Beyond the papercut, a permanently-dirty tracked file silently suppresses tooling that declines to act on a dirty tree — release scripts, git bisect, and in my case a multi-repo sync that skips repos with modified tracked files, so it skipped this one indefinitely.

📝 Walkthrough

Walkthrough

The Windows Gradle wrapper script was converted to normalized line endings. Its startup, Java discovery, error handling, execution, and exit-status propagation remain unchanged.

Changes

Gradle wrapper normalization

Layer / File(s)	Summary
Normalize Windows wrapper formatting gradlew.bat	The script’s line endings and formatting were normalized while preserving executable logic and control flow.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Poem

I’m a bunny with a wrapper so neat,
Normalized lines make the script complete.
Gradle still hops,
Java still stops,
Same exit code, same little beat!
